Objective To study the relationship between lung inflammation and lung angiotensin Ⅱ ( ANG Ⅱ) in ventilator-induced lung injury ( VILI) and assessed the efficiency of the angiotensin-converting enzyme inhibitor captopril to attenuate VILI in rats. Methods Totally 21 adult male Sprague-Dawley rats were randomly assigned into 3 groups,high-volume,0 positive end-expiratory pressure ( HVZP) group; captopril injection ( 100 mg/kg i. p. ) in 30 min before HVZP ventilation ( HVZP + CAP group) ; no ventilation group ( control) . The blood gas tensions and mean arterial pressure were measured after a polyethylene catheter was placed in one carotid artery and a plastic cannula was inserted into the trachea. The protein contents and contents of macrophage inflammatory protein-2 ( MIP-2) in bronchoalveolar lavage fluid ( BALF) and lung ANGⅡ were determined by ELISA. The changes of lung pathology were observed by HE staining. Results Mean arterial pressure was significantly lower in the HVZP + CAP group than in the HVZP group after 2 hour’s ventilation. Total protein levels were significantly higher in BALF recovered from HVZP-ventilated rats than from controls. BALF MIP-2 and lung ANG Ⅱ were significantly higher in the HVZP group than in the control and HVZP + CAP groups. Lung ANG Ⅱ level was correlated positively with BALF contents of total protein and MIP-2. Conclusion Captopril has the efficiency to attenuate VILI by reducing inflammatory cytokines. Our results suggest that VILI is partly mediated by the local angiotensin system.

Objective　In order to improve diagnosis of the disease,CT appearances of pulmonary sequestration were studied.Methods　10 cases were proved by surgery and pathology.Lung inner type was in 9 and lung exterior type in 1.All cases were examined with plain CT scans and 5 of them were taken thin slice CT scan with contrast enhancement.Results　10 cases located in the posterior segment of right or left lower lobes,3 of them were cystic,3 were solid,4 were cystic and solid.The emphysema around the lesions were showed in 7 cases.Abnormal arterial supply could be seen in 7 cases.Conclusion　CT not only can demonstrate lesions and changes of tissue surrounding lesions,but also can manifest abnormal supplying blood vessels well.CT plays important role to diagnose pulmonary sequestration.

AIM: To study the protective effect of bone marrow stromal cells (MSCs) on ischemia /reperfusion hippocampal slices. METHODS: Ischemia/reperfusion models of hippocampal slices from newborn rats were established. MSCs obtained from adult bone marrow were cultured, isolated and purified. Cell death was assessed using propidium iodide fluorescence. And brain-derived neurotrophic factor (BDNF) expression in MSCs was determined by immunocytochemistry and Western blot. RESULTS: Maximal dead cells appeared in hippocampal slices 3 to 7 days after reperfusion. When the slices were co-cultured with MSCs, only a few cells were dead. The protective effect of MSCs on the slices was diminished significantly when anti-BDNF antibody was added to the medium. The protein of BDNF was faintly expressed in MSCs under normal conditions. When MSCs were co-cultured with ischemia /reperfusion hippocampal slices, the expression of BDNF in MSCs was increased gradually especially when co-cultured for 3 to 7 days. However, MSCs co-cultured with normal hippocampal slices expressed BDNF at a lower level at any times of co-culture. CONCLUSIONS: In an in vitro model of simulated ischemia, MSCs reduce cell death. Ischemia/reperfusion hippocampal slices co-cultured with MSCs promote the expression of BDNF in MSCs, which in turn protect the ischemic neurons.
